Water Buffaloes (Bubalus bubalis) Identified as an Important Reservoir of Shiga Toxin-Producing Escherichia coli in Brazil

The presence of Shiga toxin-producing Escherichia coli (STEC) in water buffaloes is reported for the first time in South America. The prevalence of STEC ranged from 0 to 64% depending on the farm. STEC isolates exhibiting the genetic profiles stx₁stx₂ehxA iha saa and stx₂ehxA iha saa predominated. O...

Zusammenfassung:	The presence of Shiga toxin-producing Escherichia coli (STEC) in water buffaloes is reported for the first time in South America. The prevalence of STEC ranged from 0 to 64% depending on the farm. STEC isolates exhibiting the genetic profiles stx₁stx₂ehxA iha saa and stx₂ehxA iha saa predominated. Of the 20 distinct serotypes identified, more than 50% corresponded to serotypes associated with human diseases.
